1.THE PROJECT SHALL BE CONSTRUCTED ACCORDING TO THE CONTRACT AND
APPLICABLE PLAN SHEET(S), DETAILS, SPECIFICATIONS, PERMIT(S), AND/OR ANY
OTHER CONSTRUCTION DOCUMENTS (MEETING MINUTES, PUNCH LISTS, BID TABS,
ETC.) FOR COMPLETE INFORMATION ABOUT THE REQUIRED WORK. ANY ONE OF THESE
PARTS OF THE “CONSTRUCTION DOCUMENTS” MAY NOT CONTAIN ALL OF THE
INFORMATION REQUIRED TO COMPLETE THE PROJECT WORK. THE CONTRACTOR
SHALL NOTIFY THE PROJECT OWNER AND ENGINEER OF ANY CHANGES PRIOR TO
IMPLEMENTATION. THE PROJECT OWNER IS FCP AND THE ENGINEER FOR IS JENNINGS
ENVIRONMENTAL.
2.THE CONTRACTOR IS RESPONSIBLE FOR ALL UTILITY LOCATION AND COORDINATION.
ANY UTILITIES SHOWN ON THE CONSTRUCTION DOCUMENTS ARE FOR INFORMATIONAL
PURPOSES ONLY AND IN NO WAY RELIEVES THE CONTRACTOR FROM COORDINATING,
VERIFYING AND PROTECTING EXISTING UTILITIES. THE CONTRACTOR SHALL ADHERE
TO THE PROVISIONS OF THE 1985 UNDERGROUND DAMAGE PREVENTION ACT, NORTH
CAROLINA GENERAL STATUTES 887, CHAPTER 785, SENATE BILL 168, ARTICLE 3. TO
ASSIST THE CONTRACTOR AND UTILITY OWNERS IN MEETING THE REQUIREMENTS OF
THIS LAW, THERE IS A “ONE-CALL SYSTEM” CALLED “NC ONECALL.” MOST MAJOR
UTILITIES WITH UNDERGROUND FACILITIES IN THE STATE SUBSCRIBE TO THIS
SERVICE. FOR CALLS ORIGINATING WITHIN NORTH CAROLINA, THE NC ONECALL
TELEPHONE NUMBER IS 811. NO ADDITIONAL COMPENSATION SHALL BE ALLOWED FOR
DELAYS OR INCONVENIENCE SUSTAINED BY THE CONTRACTOR DUE TO UTILITY
RELOCATION OR ADJUSTMENTS MADE SOLELY FOR THE CONVENIENCE OF THE
CONTRACTOR. NO ADDITIONAL PAYMENT WILL BE MADE FOR RE-MOBILIZATION
REQUIRED BY THE UTILITY'S FAILURE TO RELOCATE A UTILITY AT THE REQUEST OF
THE CONTRACTOR. IT SHALL BE THE CONTRACTOR'S RESPONSIBILITY TO ARRANGE
FOR SUCH CHANGES, AND THE CONTRACTOR SHALL BEAR ALL COSTS OF SUCH
CHANGES.
3.FIELD CONDITIONS AND PROJECT VARIABILITY MAY REQUIRE ADAPTATION OF THE
PLANSHEETS AND/OR DETAILS PROVIDED IN THE CONSTRUCTION DOCUMENTS
DEPENDING ON SITE CONDITIONS OR PROJECT NEEDS. MINOR VARIATION(S) OR
ADAPTATION(S) OF THE PROPOSED WORK SHOWN ON THE PLANSHEETS AND/OR
DETAILS ARE CONSIDERED INCIDENTAL TO THE WORK AND WILL NOT CONSTITUTE A
CHANGE IN UNIT OR LUMP SUM PRICES.
4.THE CONTRACTOR SHALL FURNISH ALL MATERIALS NECESSARY TO COMPLETE THE
PROPOSED WORK UNLESS OTHER PROVISIONS HAVE BEEN AGREED UPON PRIOR TO
CONSTRUCTION. THE CONTRACTOR SHALL DELIVER ALL MATERIALS TO THE
DESIGNATED STOCKPILE LOCATIONS OR TO A LOCATION SPECIFIED BY THE PROJECT
OWNER OR ENGINEER. MATERIAL QUANTITIES, DIMENSIONS AND SIZES SHALL
CONFORM TO THE NOTES AND SPECIFICATIONS PROVIDED ON THE PLAN SET OR ON
THE MATERIALS LIST. THE ENGINEER MAY INSPECT AND APPROVE ALL MATERIALS
PRIOR TO CONSTRUCTION. IF MATERIALS DO NOT MEET THE MINIMUM REQUIREMENTS
SPECIFIED IN THE CONSTRUCTION DOCUMENTS, THE ENGINEER SHALL REJECT THE
MATERIALS.
5.COSTS INCURRED DUE TO PROJECT DELAYS RESULTING FROM FAILURE OF THE
CONTRACTOR TO MEET THE REQUIREMENTS OF THE GENERAL SPECIFICATIONS,
CONSTRUCTION DOCUMENTS, CONTRACTOR QUALIFICATIONS, CONSTRUCTION
SPECIFICATIONS, SHALL BE THE EXPENSE OF THE CONTRACTOR.
CONTRACTOR QUALIFICATIONS

CONSTRUCTION EXPERIENCE AND SHALL HAVE COMPLETED AT LEAST FIVE (5) RIVER
RESTORATION PROJECTS. SIMILAR EXPERIENCE WILL BE EVALUATED ON A CASE BY
CASE SCENARIO.
2.IF THE CONTRACTOR CHOOSES TO DESIGNATE AN EMPLOYEE WITHOUT QUALIFIED
STREAM RESTORATION EXPERIENCE, THE CONTRACTOR SHALL BE ON-SITE AT ALL
TIMES WHEN THE EMPLOYEE IS PERFORMING RIVER RESTORATION WORK. FAILURE TO
ABIDE BY THIS CONDITION WITHOUT PREVIOUS AGREEMENT WITH THE PROJECT
OWNER AND ENGINEER WOULD BE GROUNDS FOR TERMINATION.
3.THE CONTRACTOR SHALL MAINTAIN AT LEAST $2,000,000 IN LIABILITY INSURANCE AND
HAVE PROOF OF LIABILITY INSURANCE ON-SITE DURING THE ENTIRETY OF PROJECT
CONSTRUCTION.
4.THE CONTRACTOR SHALL HAVE PROOF OF WORKER'S COMPENSATION INSURANCE
